Hi Moloak!
I toss my vote in for all the tauren-focused guilds already mentioned in this thread.
The guild I am part of is very adventure-based, and while not a tauren tribe or tauren focused, there are a handful of incredible tauren in our cast of characters.
The Violet Vanguard are a cross-faction band of characters focused on world RP storylines, with multiple DMs to hit a variety of themes and activities week-to-week. We have active weekly guild RP sessions every Wednesday and Thursday at 5PM server / 8PM EST. We coordinate a lot on discord and in general ours is a welcoming, easy-going roster of players interested in PvE and RP.
Here’s our forum post: [H/A RP-PVE] Violet Vanguard Recruiting for Dragonflight!
Either way I hope you can find the right guild for you.
